Each 3D sound has its own listener, as the listener is associated with the 3D Audiopath. To create a 3D sound, we therefore have to load the sound into a segment. Create a 3D Audiopath for that segment. Get access to the 3D Sound Buffer contained in the Audiopath, and get access to the Listener which is also contained in the Audiopath. We can then play the sound, and alter its …
